Complement of a fuzzy set A ' ={(X 1 ,0.8) , (X 2 , 0.2)} is –

  1. A.

    {(X₁, 0.2), (X₂, 0.8)}

  2. B.

    {(X₁, 1), (X₂, 1)}

  3. C.

    {(X₁, 0.6), (X₂, 0.6)}

  4. D.

    ) {(X₁, 0.4), (X₂, 0.1)}

Attempted by 129 students.

Show answer & explanation

Correct answer: A

Complement of a fuzzy membership value is: μ′=1−μ So: For X 1 ​: 1−0.8=0.2

For X 2 ​: 1−0.2 = 0.8

Thus complement = {(X₁, 0.2), (X₂, 0.8)}
